pic18f2550 with HC-05


I'm using a pic 18f2550 and HC-05 bluetooth module, i'm running into a minor issue, but it's very hard to debug.
I'm sending and receiving data successfully, but there's always 2 extra characters being sent after the transmission from another device(my android phone)
I tried to send it back to myself, and i end up with an endless buffer of undefined characters that get to be represented by the app with the letter y with 2 dots on top of it.

Here's the code:
Just run command make to build, or make flash to build and program the chip
